Definitions

  • the present subject matter relates to the novel use of compounds of Formula (I) for protecting plants from damage caused by snails and slugs.
  • Terrestrial gastropod molluscs such as slugs, snails, etc. are major pests of horticultural and agricultural crops in many parts of the world and whose numbers increase by feeding off of these crops. Molluscs cause severe damage by feeding, and also generate unsightly mucus trails. They are considered to be serious pests of leaf vegetables, fruits, root crops, flowering plants, cereals such as wheat, barley, oats and oil seed rape, rice and also of ornamentals etc. Molluscs feed both above and below the surface of the ground, on seeds, seedlings and plants. The can damage shoots, roots, leaves, flowers and fruits therefore reducing plant stand and crop yield.
  • Slugs are a major agricultural pest causing significant crop damage because they bury themselves in the soil and eat the inside of the seeds thereby destroying the crop.
  • changes in the management of crops may lead to increased population densities of molluscs thereby resulting in further damage to the crops. These changes may include minimum tillage, direct drilling, and high organic matter build up in the soil. Slugs feed vigorously above and below the surface on seeds, growing points, shoots and roots along with other organic matter they can find.
  • moUuscicides In order to control slugs, snails, etc., a variety of extermination methods have previously been proposed. Current forms of moUuscicides are generally in the form of pellets. These usually deteriorate upon exposure to water and in particular, rain and are not sufficiently durable as long-term moUuscicides (Molluscs as Crop Pests, G.M. Barker, March 21, 2002, Technology and Engineering).
  • moUuscicides The most commonly used active ingredient in moUuscicides is metaldehyde, which disrupts the gastric organs of slugs and snails, causing death.
  • Alternatives to chemical moUuscicides include using traps or barriers, or designing gardens that are less attractive to slugs. Slug and snail baits containing iron phosphate as the active ingredient are also available. These moUuscicides provide adequate levels of control/repellency.
  • the present subject matter provides a method of controlling or repelling molluscs.
  • the method includes applying to a plant or soil in which the plants are planted an effective amount of a compound of Formula (I) wherein
  • X represents halogen
  • n 0, 1 or 2.
  • X represents fluoro, chloro or bromo, and n represents 0 or 2. In a further embodiment, X represents chloro or bromo, and n represents 2. In an even further embodiment, X represents chloro, and n represents 2.
  • the present subject matter relates to a mollusc repelling composition.
  • the composition comprises a repellent amount of a compound of Formula (I)
  • the present subject matter relates to the use of a compound of Formula (I)
  • the present subject matter relates to a composition comprising an effective amount of a compound of Formula (I)
  • agriculturally acceptable carrier means carriers which are known and accepted in the art for the formation of formulations for agricultural or horticultural use.
  • plant or “crop” includes reference to whole plants, plant organs (e.g. leaves, stems, twigs, roots, trunks, limbs, shoots, fruits etc.), plant cells, or plant seeds. This term also encompasses plant crops such as fruits.
  • plant may include the propagation material thereof, which may include all the generative parts of the plant such as seeds and vegetative plant material such as cuttings and tubers, which can be used for the multiplication of the plant.
  • This may also include seeds, tubers, spores, corms, bulbs, rhizomes, sprouts basal shoots, stolons, and buds and other parts of plants, including seedlings and young plants, which are to be transplanted after germination or after emergence from soil.
  • controlling refers to the ability of the compound of the subject matter to have a detrimental effect on the mollusc such as by preventing, combating, eradicating, destroying, repelling molluscs, increasing the mortality, inhibiting or reducing the growth and/or development of molluscs, paralysis, feeding inhibition and killing of molluscs. It may also include protecting plants from mollusc infestation and/or damage.
  • mollusc refers to gastropod molluscs like terrestrial animals such as slugs, snails, etc., aquatic or marine animals such as mud snails, barnacles, etc.
  • the term "effective amount” refers to an amount of the compound that, when ingested, contacted with or sensed, is sufficient to achieve a good level of control.
  • mixture or “combination” refers, but is not limited to, a combination in any physical form, e.g., blend, solution, alloy, or the like.
  • post-emergence refers to the application of the molluscicide composition to the plants that have emerged from the soil.
  • pre- emergence refers to the application of the molluscicide composition to a habitat, or soil, prior to the emergence of the plants from the soil.
  • endpoints of all ranges directed to the same component or property herein are inclusive of the endpoints, are independently combinable, and include all intermediate points and ranges. It was found that a mollusc population may be repelled and/or controlled by applying to the plant or to the soil in which the plants are planted an effective amount of a compound of Formula (I)
  • X represents halogen
  • n 0, 1 or 2.
  • X represents fluoro, chloro or bromo, and n represents 0 or 2. In a further embodiment, X represents chloro or bromo, and n represents 2. In a specific embodiment, the compound is fluensulfone when X represents chloro, and n represents 2.
  • the present subject matter relates to the use of a compound of Formula (I) as defined hereinabove for controlling and/or repelling a mollusc population on plants or soil in which the plants are planted.
  • the plants or soil in which the plants are planted are infested with said molluscs.
  • the compound of Formula (I) as defined hereinabove may also be used to protect stored products from molluscs.
  • the effective application rates of the compound of Formula (I) cannot generally be defined, as it varies depending upon various conditions such as the type of the formulation, weather conditions and the type of crop.
  • the application rates of the compound of Formula (I) may vary depending on the desired effect. In an embodiment, depending on the desired effect, the application rates according to the present subject matter may be from approximately lg/ha to approximately 5000 g/ha. In another embodiment the application rates according to the present subject matter may be from approximately 1000 g/ha to approximately 4000 g/ha. In a specific embodiment, the application rates according to the present subject matter may be 2000 g/ha. The optimal rate for a specific application will depend on the crop and may be readily determined by established biological tests known to those skilled in the art.
  • the present subject matter further relates to a mollusc repelling composition comprising a repellent amount of a compound of Formula (I) as defined hereinabove. In a specific embodiment the composition may further include an agriculturally acceptable carrier.
  • the composition may include at least one additional component selected from the group of surfactants, solid diluents, liquid diluents and other additives.
  • the active compounds according to the invention can also be used in a mixture with known herbicides, fungicides, bactericides, acaricides, nematicides or insecticides, plant growth regulators, biostimulants to widen, for example, the activity spectrum or to prevent the development of resistance. In many cases, this results in synergistic effects, i.e. the activity of the mixture exceeds the activity of the individual components. However, for the avoidance of doubt it is understood that such additional crop protection agents are unnecessary to achieve the effects of the present combinations. Accordingly, the present mollusc repelling composition may be limited to containing a compound of Formula (I) as the only crop protection agents.
  • compositions can be made at the time of use, or diluted.
  • the present compositions can also be concentrated compositions, or so-called “ready-to-use” compositions, that is to say, compositions ready for use.
